摘要：
A novel reconfigurable digital filter has been proposed for a mobile terminal receiver that can drastically reduce power dissipation dependant on adjacent channel interference. It automatically scales the number of filter coefficients by monitoring the in-band and out-of-band powers. This new filter performance was evaluated in a simulation UTRA-TDD environment because of the large near far problem caused by adjacent channel interference from adjacent mobiles and base stations. The UTRA-TDD downlink mode was examined statistically and results show that this reconfigurable filter can save an average of 75% power dissipation when compared to a fixed filter length of 41. This will prolong talk and standby time in a mobile terminal. The average number of taps was calculated to be 10.1 for an outage of 97%.
